I think Anakin would still kill all of the Tuskens, because they hurt his mother.

I beleive his sense of duty holds him to helping Obi-Wan. After Obi-Wan is saved and He and Padme are married, he is supposed to come back to the Jedi Academy, but he refuses and he goes to check on his mom.

(The message is intercepted by Lord Sidious. He sends Dooku who catches Clegg and Shimi on an errand to Mos Esley and are killed by lightsaber)

Obi-Wan is sent to Tatooine to retrieve Anakin. On route, Anakin is told by the counsel that if he does not come back to the order, he will be punished. He turns off communications.

Obi-Wan arrives just before Anakin. Obi-Wan sees something smoking a few kilometers from the Lars' homestead. He takes a detour to find that Cleggs speeder is burning. He sees Dooku leaving and giving fast pursuit, catches Dooku. They fight and Obi-Wan kills Dooku. When Obi-Wan arrives back to the wrecked speeder, Clegg has been cut down and dead and Shimi is in great pain and is going to die. With her last breaths, she tells Obi-Wan that Padme had just sent a communications to them (since she couldn't get a hold of Anakin)that see is pregnant with Anakin's child. Shimi is in so much pain, she asks Obi-Wan to give her peace. He pulls out his lightsaber and gives her, her final wish. At that very same moment, Anakin comes up on Obi-Wan. He doesn't ask questions, he just keeps screaming you killed her.

Obi-Wan defeats Anakin by knocking Anakin's saber out of his hand and force pushing him closer to the wrecked speeder. But before Obi-Wan can explain, the speeder explodes, engulfing Anakin in flames. (Only Anakin's hatered keeps him alive)

Anakin is discovered by Darth Sidious who is checking on Dooku. When he sees Anakins whithered body, he puts back his hood and takes Anakin aboard his ship. Palpatine drums up some papers that make it look like the Jedi Counsel sent out Jedi to kill Anakin's parents and make it look like sith did it to bring him back to the order.

Obi-Wan tells the counsil what happened and the counsil tells Obi-Wan to hide Padme and the unborn child (children).

Wow. Kevin, that is just so believable. Maybe you need to start writing a fanfilm or something to that extent.

I always visioned Anakin returning to free his mother from slavery and there being this huge battle between the Jedi and Droid Army, and Obi Wan accidently kills Anakins mother in front of him while trying to save her, like a deflected blaster shot that hits her. Thats when Anakin turns on the Jedi Order and hunts down the Jedi and saves Obi Wan for last so that he can witness what has happened.
